Adom Hydrogen

For the main AH/Claude build thread: John asked for a larger widget hover surface, and specifically suggested moving/resizing the existing WebView2 frame so it expands on hover and returns to the title bar on mouse-out. The implementation is built and tested in an isolated WebView2 fixture.

Core PR (private source stays private): https://wiki.adom.inc/adom/hydrogen-dev/prs/1 AI Flow responsive client: https://wiki.adom.inc/adom/adom-aiflow/prs/7 (additive to PR #6).

The same frame and page remain alive. Hydrogen owns its expanded position and size while reserving the original title-bar slot. The widget adapts through its ordinary resize/media queries. Existing widgets remain unchanged unless they opt in. AI Flow shows larger cached images, captions and selectable thumbnails without extra AI calls. Pinning keeps it open; Escape from the child and mouse-out restore the small surface.

Checks passed: actual modified Svelte component production build in the fixture; hover/out/reopen with the same iframe and document timeOrigin; selected-image retention; resize alignment; pinning; child Escape; foreign-sender rejection; explicit opt-out; 20px compact layout; larger-cache creation and disabled/outside-run checks. Screenshot attached. The full mirrored application check has unrelated missing/generated-module errors, so I have not claimed a Windows release build.

Please integrate into the maintained AH checkout, run the native Windows build/release checks and ship it through the usual channel.
